VENTED WATER-CLOSET.

Patented Apr. 1%, 1916..

Application filed August 29, 1910. Serial No. 579,582.

To all whom it may concern:

Be it known that I, CHARLES H. MUCKEN- HIRN, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Vented ater-Closets, and declare the following to be a full clear, and exact description of the same, such as-will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to water closet bowls.

It has for its object an improved arrangement of waterv inlet passage and air outlet,

or vent passage by means of which airis taken from the top of the bowl above the flushing water and the flushing rim is provided at the rear adjacent to the air passage with a sinking or diving passage that delivers water underneath the inlet of the air passage producing a continuous flushing extending entirely around the bowl with the vent passage leading out from the bowl above the sinking or diving passage and from a high part of the cavity within the bowl.

In the drawings: Figure 1, is a Vertical longitudinal section of the entire bowl and seat. Fig. 2, is a horizontal section along the broken line aa of Fig. 1. Fig. 3, is a rear elevation partly in section at the line b-Z) of Fig. 1. Fig. 4, shows a similar construction with a vertical water inlet passage at the rear of the bowl. Fig. 5, is a plan view of the rear part of the bowl. Fig. 6, is a rear view partly in section taken along the broken line cc of Fig. 4.

The seat attachment of Fig. 1 is an in- .clined seat with a vertical seat holding bracket. The seat of Fig. 4 is a horizontal seat with ordinary pin connections.

Referring to the form shown in Fig. 1, the bowl 1 is provided with a flushing rim 2 extending around the front and the sides thereof. The water inlet 6, in this instance, is a horizontal-inlet leading into the bowl at the middle of the rear face; just within the body of the bowl the passage divides and one branch 6 leads to one end of the flushing rim, and the other branch 7 leads to the other end of the flushing rim. 4: designates the vent outlet passage located between the said ends of the rim, and continuing to the rear as a horizontal duct 5. For the purpose of flushing the front wall of the siphon passage a flushing chamber 8 is fomed in the rear of the closet at the top of the siphon passage and provided with a flushing openmg located immediately at the top of the wall 9. The flushing chamber 8 connects at its opposite ends with the water passages 6 and 7. This peculiar construction of the closet with the flushing rim terminating at opposite sides of the rear wall of the bowl, is had for the purpose of providing a vent passage 4 leading from a point near the top of the bowl directly rearward in a straight line'and terminating preferably at the rear of the closet. In this form of construction the seating rim is inclined with the forward edge on a higher plane than the rear edge and the hinge connections for the seat and tlzgver therefor are made as a vertical bracket In the form shown in Fig. 4, the water inlet passage 16 enters at the rear of the bowl from above and drops vertically for a short distance until it meets the entrance 17 of the outlet passage 15, thence continues as an annular chamber to the lower side of the walls surrounding the vent passage 15 and thence spreads to the side passages 13 with a return branch 18 that furnishes flushing water to the extreme rear of the bowl cavity. The vent passage 15 opens from the bowl above the rear water passage or chamber 18 and between the side passages 13 and discharges from substantially the highest part of the bowl and extends directly to the -rear through a horizontal passage which is without obstruction.

In both forms the vent passage is-central to the rear part of the bowl, extends substantially horizontally to the rear and is unobstructed throughout the entire part of it which is contained in the bowl. Both bowls are (as shown) of siphon jet construction, one of them with the flat seat in common use, and the other with the inclined seat also in common use. In either form of construction the flush water washes the entire inner face of the bowl and by proper proportioning of the holes or slots may be distributed as desired. This form of vent may be employed with any of the commercial varieties which employ a pushing rim, in which however so is most desirable and in the other form the outlet is thrown far forward toward the center of the bowl, when the air is apt to form an eddy because of the (generally) gyrating water and the discharge of air is delayed.

What I claim is 1. A water closet bowl provided with a flushing rim, a vent duct leading from the bowl and on a plane with the flushing rim, and a flushing passage located below the vent duct to prevent obscuring of the vent duct by the flushing water and permitting the air currents set up by the water of the flushing rim to pass directly into the vent duct.

2. A water closet bowl provided with a flushing rim, a vent duct leaving the bowl cavity on a plane with the flushing rim, and a flushing chamber dipping below the vent duct, whereby obscuring of the vent duct by the flushing water is prevented and the air currents set up by the bowl are directed to the vent duct.

3. A water closet bowl provided with a flushing rim extending around the front and along the sides of the bowl, a vent passage extending between the sides of the rim in the plane thereof, and a flushing chamber dipping below the vent passage at the rear of the bowl and provided, with a water outlet along said dipping part, whereby obscuring of the vent passage by the flushing water is prevented and the air currents set up by the flushing of the bowl are directed to the vent passage.

I. A water closet bowl provided with a flushing rim, a vent duct leading from the bowl and on a plane with the flushing rim, and means for flushing the rear wall of the bowl below the vent duct without obscuring the vent duct so that the air currents set up by the flushing water will pass directly into thevent, substantially as described.

5. A water closet bowl provided with a flushing rim for the bowl extending around the sides and front thereof, an apron depending between the sides of the flushing rim at the rear of the bowl, and avent passage extending rearwardly from between the sides of the flushing rim at the rear and in the plane thereof to the rear of the bowl.

6. A water closet bowl provided with'a flushing rim for the bowl extending around the sides and front thereof, an apron depending between the sides of the flushing rim at the rear thereof, a vent passage extending rearwardly from between the sides of the flushing rim at the rear and in the plane thereof to the rear of the bowl, and supply ducts for the opposite sides of said flushing rim.

7. A water closet bowl having a flushing rim around its edge, water supply passages for the 'rear ends of the rim extending rearward on opposite sides of the center, a supply passage with which the rear ends of the rim supply communicate, a vent passage leading rearward through the bowl within the plane of the flushing rim and extending between the supply extensions of the flushing rim, and a flushing branch in advance of the union between the supply passages for the rim and the main supply and extending from one of the side supplies to the other and below the vent passage.

8. A water closet bowl having a flushing rimaround its edge, water supply passages for the rear ends of the rim extending rearward on opposite sides of the center, a supply passage with which the rear ends of the rim supply communicate, a vent passage leading rearward through the bowl within the plane of the flushing rim and extending between the supply extensions of the flushing rim, and means for directing flushing water from the supply passages to the bowl in advance of the union between the supply passages for the rim and the main supply below the vent passage.

In testimony whereof, I sign this specification in the presence of two witnesses.
